Description:
   Rounds a number to the specified number of places

Parameters:

1. number (Numeric, required)
          The number to perform the rounding operation on.
   
   
2. precision (Numeric, Default: 0)
          The number of decimal places to leave in rounding operation. If this number is -1 the number is passed through the function unprocessed.
   
   
3. alt_precision (Numeric, Default: )
          If the integer section of the number is zero this alternate decimal precision can be used.
   
   

Returns:
       

Requires:
